A power cut in the middle of cooking is what F04 reports on Miele steam ovens and combination steam ovens.

At a glance

Code F04
What it means Power supply interrupted during a programme.
What you can check Turn the oven off, turn it on again and restart the programme. If cooking had progressed, set a new cooking time where needed and press Start/Stop to carry on.
When to call a technician Arrange a service visit if F04 keeps appearing after the restart. Note whether it happens at the same point in a programme each time.

The DGC 7450 manual words it as “Power cut – process cancelled” and blames a brief interruption that stopped the running cooking programme. Its instruction is to turn the oven off, turn it on again and restart the programme.

Quick recovery

  • Look at the cooking progress.
  • Set a fresh cooking time when one is needed.
  • Hit Start/Stop and the programme carries on.

Codes that look similar

  • F235: an electronic module fault, which is not an interrupted supply.
  • F05: the water intake valve is not fully open, or the nozzle is scaled or clogged.
